Could customer oder more device in one pledge?

Yes,According to Kickstarter's rules, backers can only choose one reward tier per pledge, which means you currently cannot add more devices to your existing account directly. However,We discussed a solution where you can manage your pledge and you can add a corresponding bonus to get an extra Max2 based on the Super Early Bird price. We will get in touch with you post-campaign to ensure that the product is shipped to you at the price and quantity you expect.
